Did you get the App Access Blocked Outlook error on your smartphone?
It may prevent you from viewing emails, attachments, contacts, calendars, and more from your work Outlook account.
You’ll also see the same message if you try to log in to the sameOutlook emailusing any mobile browser, likeMicrosoft Edge.
This error is often linked to the Microsoft Intune app management service. It’s a cloud-based system that allows company admins to restrict an organization’s data from being copied or accessed over insecure networks.
Luckily, I’ve reproduced the issue and discovered some fixes. I’ll show you how to resolve it below, so let’s get into it!
How To Fix App Access Blocked Outlook
Here are a few troubleshooting ideas to try before contacting your organization’s Microsoft 365 administrator or the IT admin. I arranged them based on complexity.
Perform Some Initial Checks
The Intune MDM app and service are there to protect an organization’s sensitive data and prevent unauthorized access to such data. Before troubleshooting, confirm the following:
Clear Cache and Cookies
If you’re attempting to open Outlook on an iPhone or iPad,swipe up from the bottomof the screen and let go of it in the middle of the screen.
You’ll see a carousel of apps. This is theApp Switcherfor iOS devices.
Scroll the app carouselleft or right to find the Outlook app. Tap on the app card and swipe it up.
This will force close the app and all of its cache and cookies.
Now, open the app from theHome Screen.
Should you need to wipe the cache and cookies data of Outlook on Android, perform these steps instead:
Update Outlook
Intune MDM and MAM-managed apps require updating when a new version is available. Though the Intune app automatically downloads and installs the latest updates, it might not work if you don’t allow updating via mobile data.
Try these steps now on an iOS device:
If you’re on an Android device, open theApp infoscreen and find Outlook.
Now, scroll to the bottom and tap on theApp detailsmenu.
TheGoogle Play home screenfor the app will open.
If there’s a new version, you’ll see theUpdatebutton. Tap on that.
Scan For Viruses and Malware
Now, try to access the Outlook email client or web app again.
Review App Permissions
Managed devices running company apps through the Intune app require full access to the following app permissions;
If you or the smartphone settings make any changes to the required permissions, the security features of the Intune MDM and MAM might not let you access any assigned apps, including Outlook. Do the following to fix this issue on an iPhone:
On an Android device,long-tapon the Outlook icon and then tap on the(i) iconin the top right corner of the context menu.
On theApp infopage, tap on thePermissionsmenu.
Now, you can browse through the necessary permissions and grant them.
Remove the Account and Sign Up With Intune
Sometimes you may attempt to sign in to Outlook using a work account. However, your company might need you to do that through the Intune Company Portal.
In that case, tapRemove Accounton the error screen to delete the work email. Now, follow these steps:
Add the Outlook App to the Intune Console
It’s likely that Outlook isn’t available in the approved or whitelisted app list in the Intune portal. As the Microsoft 365 admin or IT admin, you can perform these steps to fix the issue:
It might take a few minutes for the changes to take effect globally in your Microsoft 365 domain. Ask your tenant users to test their Outlook app now.
